When hydrogen nuclei are fused together to form a helium nucleus, the mass of the product is 0.7% less than the mass of the reactants. If 1 gram (1 x 10-3 kg) of protons were completely fused into helium nuclei, the mass of the helium nuclei
produced would be 6.8 x 10-6 kg less than the mass of the protons.
Using the equation E = mc2, calculate how many joules of energy would be produced by converting 6.8 x 10-6 kg of matter
into energy in this fusion reaction. Use c = 3 x 108 m/s.
E = 6.05 x 1011 kg x m²/s2
E = 6.10 x 1011 kg x m2/s2
E = 6.12 * 1011 kg x m2/52
E = 6.25 x 1011 kg * m/s2
E = 6.30 x 1011 kg m/s2

Scenario 5 1) take 10 red and 10 black beans and place them, mixed, on the table. record the starting phenotype # and frequencies (% of your total population) of your starting population in the table provided (generation 0). 2) act as a predator. “capture” as many organisms as you can until you have reduced the population to three organisms. put them aside. at this point, the predators die. 3) the remaining organisms each produce 2 clonal offspring. multiply your organisms accordingly and allow them to mix on the table. calculate and record the resultant phenotype # and frequencies (% of your total population) of your population in the table provided (generation 1). 4) repeat the reproduction event, allowing each of your organisms to produce 2 clonal offspring. calculate and record the resultant phenotype # and frequencies (% of your total population) of your population in the table provided (generation 2). 5) repeat the reproduction event, allowing each of your organisms to produce 2 clonal offspring. calculate and record the resultant phenotype # and frequencies (% of your total population) of your population in the table provided (generation 3).

Up until 1938, paleontologists accepted the idea that coelacanths (an ancient fish) went extinct at the time that they last appear in the fossil record, about 80 million years ago. but in 1938, a live coelacanth was discovered off the coast of south africa that was compared to the fossil record and found to be the same species what goal of science does this discovery represent
